Method for treating a patient having precancerous lesion with 4-phenylphthalazine derivatives

Derivatives of 4-phenylphthalazine are useful for the treatment of patients having precancerous lesions. These compounds are also useful to inhibit the growth of neoplastic cells.

Synthesis and Reactions of Phthalazine Derivatives

Hydrazones (Ia-c) fail to undergo cyclisation under different conditions to yield phthalazines (IIa-c). o-Aroylbenzoic acids (IVa-c) on treatment with hydrazine hydrate give 4-aryl-1(2H)-phthalazinones (Va-c) which react with POCl3 to yield 4-aryl-1-chlor
